In the matter of ViaCad. I`ve asked on their forum. Only ViaCad Pro has got ACIS kernel modeling tools. ViaCad 2d/3d doesn`t. It changed lately. It`s not so cheap to buy it only for fillets.


There is some open source kernel OpenInventor (Coin3d framework). If Inventor has better fillets than MoI3d and Rhino then why someone won`t build paid plugin for both with using that kernel? I think many people would buy it. Only for fillets, offsets and shelling (if its better). I`ve heard that some of FreeCAD users want to implement that kernel in FreeCAD (I think I`ve heard it here about future plans of changing freecad: https://www.youtube.com/watch?v=7Z-GBpV97q8)
